Comin to a more specific description of I- rim shown'in the drawings and Ithe parts bein assumed to loosely occu y the positions s own in Fig. 1 with the tire de# lated, it is apparent that by virtue of the inclined face B and the seat B? the tire-inflation will ofv its ownaccord and Without any manual assistance automatically seat the flan e B against the locking-ring C and that thel ateral outward pressure exerted by the rim Bwill cause a radially inward or contracting pressure upon the ring C to automatically additionally contract it, and thus lock the groove A3 ,an

it into place. This feature, by virtue of which the .rim flange automatically seats itself upon the'locking ring and thereafter exerts Ta radial contracting pressure thereupon, is another important feature of InyinventiOn. Itis equally plain thatin order to remove the tire upon deflation itis necessary to force the flange B inward 4toward the flange A', thus freeing the lockingring C, Whichcan then bes rung straight u out of across the e e A. Thereupon the flan e B slides outwar y over the ed e A2", and t e selvage T' of the tireshoe fo lows.

The locking-ring C may be made of an end'- less piece of wire rope which has sufficient extensibility to be readily sprung, and thus contracted into the groove A. Thel contracting pressure of the ring B will cause the fibers' of the rope to shorten sufficiently to prevent the rin from juni ing out of the groove. Instea of a rin ci) rope I may use This may e curved in crosssection an of a shape suitable for coperating with the inclined face B. Y,'.lhe curved cross-section of the locking-ring is automatally adapted, as it were, to cooperate with the inclined face on the rim-ange. A peculiarly useful form of lockinglL-in is drawn in Fig 3. It consists of a he o Wire having its ends joined in ring forni. L

In order that the tire shoe *may readily slip'off and on the Wheel ri1n, its selvages should embrace the rim loosely. Inflation of the-tirewould thus leave the selvages with-v out a uniform seat against the rim.- The Wedge-shaped foot B3 provides a seat which adjusts itself to varyin degrees of looseness of the selvage and'pro uces a peculiar tight or antichang fit of the parts.

It should perhaps be mentioned that the face B, which contacts With the ring C, is inclined with reference to the rim-surface and not necessarily with reference to the adjacent outer faces of the rim-flange B.
